Need suggestion for fish addition

[craigj]

In my 20G FO tank, I currently have a 2 inch tomato clown and 2 inch strawberry basslet. I want to add one more fish and am not sure what. Both of my current fish are fairly aggressive feeders so a somewhat aggressive fish is needed. Any suggestions? By the way, there is no live rock in the tank so a dwarf angel is out of the question.

Have you thought about an orange-tail blue damsel. Not too expensive, aggressive feeders, heck you could just say agreessive and they don't get huge.
